Systems and methods for secure payment processing are disclosed. An issuer vault generates payment items, which correspond to consumer account information and which replicate the structure of the account information but do not include consumers' actual account number. The payment items, rather than the actual account information, are communicated to on-line and mobile payment services for use by consumers in payment transactions. When a consumer uses a payment item in a payment transaction and the transaction undergoes authorization processing, the payment authorization network uses the payment item to request and receive the actual account information from the issuer vault. The authorization network uses the actual account information for the limited use of authorizing the transaction. Once the transaction has been authorized using the actual account information, the processing of the transaction continues using the payment item information rather than the actual account information.

4. The computer implemented method of claim 3, wherein the vault search server searching the vault database for and identifying an account requiring a payment item comprises the issuer vault system identifying that a threshold has been met, the threshold identifying a minimum number of payment items associated with an account.
5. The computer implemented method of claim 3, wherein the vault search server searching the vault database for and identifying an account requiring a payment item comprises the issuer vault system identifying that a threshold has been met, the threshold identifying a minimum number of payment items associated with a virtual wallet.
6. The computer implemented method of claim 3, wherein the issuer vault system comprises the issuer vault system updating the vault database to include the generated at least one payment item and data identifying a relationship to the identified account requiring a payment item.
7. The computer implemented method of claim 1, wherein the request for an account number further comprises a request for an acquirer identifier uniquely identifying an acquirer entity corresponding to the merchant interface of the acquirer system, a payment transaction number, a payment transaction date and time, and a payment transaction amount.
8. The computer implemented method of claim 7, wherein the issuer vault system comprises storing in computing memory for each payment item an indication of whether or not a corresponding account has been compromised.
10. The computer implemented method of claim 8, wherein the indication of whether a corresponding account has been compromised comprises an indication of whether a payment card corresponding to an account has been lost.
11. The computer implemented method of claim 8, wherein the vault database data includes an expiration date and expiration time for the payment item associated with the received temporary identification number.
14. The system of claim 13, wherein the vault database comprises data identifying a number of payment transactions completed using the payment item associated with the received temporary identification number and data identifying a maximum number of payment transactions allowed using the payment item associated with the received temporary identification number.
16.
